Following the completion of a Phase I and II Geoenvironmental Assessment and the establishment of a Remedial Strategy, based on a Human Health Risk Assessment and CLER guidelines the Remediation of a former reservoir site was completed. Infill materials (brick and concrete debris, clay soils contaminated with diesel range organics was excavated. Preliminary treatment of some volumes of soils allowed re-use as general filling of the site, where due to gross contamination the remaining material, less concrete and brick debris removed via a screening plant, was relocated off-site to a licensed landfill.
Contaminated soils were removed down to natural strata – Glacial Till/boulder clays, as detailed in a photograph of the Remediation Works, with clean imported soils used to bring the exposed surface up to design levels. The site was then available for residential development.
